From 1165e150d5867c3bbcae559c0d09076000b8cf9d Mon Sep 17 00:00:00 2001 From: Natanael Copa Date: Wed, 20 Dec 2017 12:00:57 +0000 Subject: [PATCH] configure: test for getaddrinfo_a and libanl Test for the existence of the GNU extension getaddrinf_a and libanl instead of assuming that every Linux has it. Fall back to posix variant if they are missing. This fixes build with musl libc which does not implement this GNU extension.
